Career
Isabella was the elder of two children, she had one younger brother Humphrey. From their mother"s third marriage to Raynald of Châtillon, the pair gained two half-siblings: Raymond, who died young and Alice, who married Azzo VI of Este. Ruben and Isabella were only married for around five years, in which time Isabella bore two daughters:
Alice (1182 – after 1234), the wife firstly of Hethum of Sassoun, secondly of Count Raymond IV of Tripoli, and thirdly of Vahram of Korikos
Philippa (1183 – before 1219), the wife firstly of Shahanshah of Sassoun, and secondly of Theodore I Laskaris, emperor of Nicaea
In 1183, Ruben was taken captive and imprisoned by Bohemond III, Prince of Antioch, during Ruben"s visit to Antioch.
He was released after the payment of a large ransom to the Prince of Antioch.
Later life
Isabella never remarried after Ruben"s death. Her brother-in-law Leo was initially the "Regent and Tutor" of Alice and Philippa but he eventually set them aside and was succeeded by his own descendants.
Both of Isabelle"s daughters were married roughly around the same time in 1189. In May, 1193, their spouses were both murdered.
Toron remained in Crusader possession until 1187 when it fell to the forces of Saladin after the Battle of Hattin when Saladin all but destroyed the Crusader states.
Toron was recovered through the Treaty of Jaffa in 1229 and Alice succeeded as Lady of Toron, passing the title on to her descendants.
